I work primarily in JavaScript and Python but have recently returned to school where I am learning Java.
In recent years, I've been falling increasingly down the GIS rabbit hole--mostly using GeoDjango and Leaflet.
This co-mingled mal-formed excel reports and time clock data for aggregation and comparison. Dataset was full of holes.
